SVG to Data URI Converter processes your raw vector code into a self-contained URI string (`data:image/svg+xml,...`). A Data URI allows you to completely embed a graphic directly inside an `<img>` tag's `src` attribute or within a JSON payload without needing to host an external `.svg` file. It prevents frustrating CORS blocking issues and stops unnecessary network requests.
A Data URI is a scheme defined by RFC 2397 that allows creators to include small data items inline, as if they were referencing an external resource. For SVGs, this tool calculates the optimal URL-encoding (escaping unsafe characters like quotes and hashes) and affixes the standard mime-type header (`data:image/svg+xml,`). The browser interprets this string identically to a real file download.
For SVGs, URL-encoding (which this tool uses) is highly recommended. Because SVG is plain text, Base64 simply inflates the size by 30% and ruins GZIP compression. URL-encoding keeps it smaller and maintains standard CSS/HTML compatibility.
Yes! You can use it exactly like a link. Simply paste the output into the `src` attribute: `<img src="data:image/svg+xml,...">`.
For small graphical elements (under 10KB), it improves speed by skipping DNS lookups and TCP handshakes. However, embedding massive, complex illustrations as Data URIs can bloat your HTML file size and delay the initial browser parsing.
The `#` character (used in hex colors) will completely break an unencoded Data URI. Our tool automatically percent-encodes `#` to `%23` and handles all other unsafe characters so it works flawlessly.
No. The conversion is purely structural and executes locally inside your web browser.
Yes, it is fully free to use for unlimited conversions.
